João Pedro Silva Ah, now I see it! You can only see the head and the rhinophores and part of the parapodia of this Elysia viridis!
João Pedro Silva Did you spot it while shooting or only after seen the photo on the computer screen? I've gathered a few dozens of what I call "uninvited guest" photos. The most dramatic find was of a Cuthona caerulea on a photo of a Flabellina babai... and it was found two and a half years after the shot was taken :)
João Pedro Silva This is my "uninvited guests" set on Flickr. Many nudibranchs but also parasites, copepods, shrimp, etc:
